A new sheet music file for this arrangement is for synth pad - this replaces the synth strings part if you want to get that modern worship sound (use the regular synth strings with other orchestral instruments.) You of course can never get these modern arrangements to sound exactly like the recordings unless you use multitracks, but you can approximate the sound with this synth pad part - it's exactly what I'm playing for the core synth you hear. For those who are high-tec and using laptops and soft synths, I'm using Peter James' ZION patch for Omnisphere. This is the exact sound he has used on Hillsong recordings and you can download it at multitracks.com.
This recording uses several layers of electric guitars. Like synths, you'll never be able to reproduce the track exactly without multitracks, but the guitar spotlight MP3 will help your guitarists get close by hearing clearly exactly what's going on.
Modern: Use multitracks or the synth pad sheet music instead of the synth strings.
Blended: Synth strings and instrumental parts sheet music.
Acoustic: Cello sheet music, use brushes with drums.
